CHAIN GUIDE non 001m nnvnnns.

Application filed September The object of my invention is to provide a chain guide for corn binders of simple, durable and comparatively inexpensive construction.

'A further object. is to provide guides designed to fit on corn binders for the purpose of guarding the gathering chains against becoming displaced, while the machine is be ing used for cutting and binding corn.

WVith these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a plan view, showing the frontends of the gathering chutes of a corn binder with my guides attached thereto.

Figure 2 is a sectional view on the line .22 of Figure 1. c

Figure 3 is a sectional View on the line 33 o1. Figure 1.

Figure L is a perspective view of one of my guides; and

Figure 5 is a perspective view or the other guide.

In the accompanying drawings, I have used the reference numeral 10 to indicate the gathering chain 'boardson which are mounted the sprockets 11 and the flanged guide wheels 12. The gathering chains 18 extend around the sprockets 11 and Wheels 12. On the chains 13 are the corn gathering fingers 14. I

Strips 15 and 16 arebolted back of the chains 13 to prevent the chain being pushed away from the corn in the gathering process. The foregoing is all of the usual corn binder construction, and forms no part of my present invention.

In the practical use, I have found that if the chain 13 becomes too loose as with wear, it frequently becomes displaced from the wheel 12 and then replacement is necessary in order to keep the binder in operation. It the grain of the board 10 or strips 15 and 1G happens to be against the direction of the travel of the chain, they become splintered, sometimes so badly that their replace- 30, 1925. seriai No. 59,517.

ment is necessary. This causes inconvenience serted under the stripslo' and 16, and held in place by the bolts 20, whichoriginally held only the strips.

At the forward ends of the-guides 17 and 18,-at the point where the fingers let come onto them, I provide downturned portions 21 so that the fingers 14 will not catch on the guides. i

I have considerably used scribed on my binder and find them very satisfactory, and also find that they entirely eliminate any danger of the chains 13 coming oil the sprockets 14 or wheels 12.

Although I have illustrated my guides on corn binder, they may also be used on corn pickers, shredders, etc. to perform the same function.

It will thus be seen that I have provided efiicient and simple guides for the chains and some changes may be made in the construction and arrangement of the various parts of -my invention, without departing from the real spirit and purpose of my invention. and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included withintheir scope.

I claim as my invention r 1. In combination with a gathering board having a gathering chain, extending adjacent the edge thereof, a chain guide comprising a strip of metal secured to said gathering board and having an extending portion beneath said chain for supporting it, one corner of said guide being bent downwardly.

2. In combination with a gathering board having a gathering chain extending adjacent the edge thereof, and a chain backing strip secured to said board, a chain guide comprising a strip of inetal secured to said gathering board beneath said backing strip and having an extending portion beneath said chain for supporting it, one corner of said guide being bent downwardly.
